Greetings- I need an 18 inch spare to fit in the "wayback" well of my 2002 Audi S6 Avant (recently O1E 6 speed converted!) . I also Converted the original S6 brake calipers to the RS6 8 pot Brembos and the rotors to the 365mm RS6 standard. I'd have to do some juggling if I were to get a flat on the front of the car as my stock spare won't fit over the 8 pot Brembos. Any help would be greatly appreciated. thank you, Paul, Providence, RI
